+     a. If Type(value) is Object and value has a [[DateValue]] internal slot, then
+        i. Let tv be thisTimeValue(value).

+        ii. If Type(v) is String, then
+            1. Let tv be the result of parsing v as a date, in exactly the same
+               manner as for the parse method (20.3.3.2). If the parse resulted
+               in an abrupt completion, tv is the Completion Record.
